To all whom it may concern."

Fe it known that l, FRANK d. lDnUAn, a

citizen of the lUnited States, and residing at Detroit, county of Wayne,State of ll/lichigan, have invented certain new and useful Improvementsin Attachments for Motor-'Vehicle Radiators, of which the following is aspecification.

The presentinventlon relates to moto 1u vehicles and more particularlyto means to 15 cover for the front of the vradiator and attaching meansfor detachably securing the curtain thereto. l

@ther objects and'features of novelty will be apparent from thedescription taken in au connection with the drawings in which:-

Figure 1 is a front elevation of a radiator provided with a curtainconstructed 1n aci cordance with the present invention, a portion of thecurtain being shown broken 25 away and folded to illustrate the mannerof varying the size of the opening in the radiator;

Figure 2 is a sectional elevation through the curtain and attachingmeans taken subrel.

Figure 3 is an enlarged sectional plan view taken substantially on theline33 of Figure 1; and i Figure 4f is a front elevation of a removaaable frame employed for securing the curtain to the radiator.

Referring to the drawings it will be seen that theinvention isillustratedlin connection with a radiator of the usual type comiioprising a core surrounded by a removable shell 11. For the purpose ofsecuring the shell to the core, the core has the rearwardly extendinghngers or .tongues 12 which are bolted or otherwise fastened to the Atcertain times of the year it is desirable to close or reduce the size ofthe opening in the front of the radiator through which air passes..lAccording to this invention, is accomplished by providing a curtainsimilar in outline to the radiator air opening and detachably securinthe same at its marginal edges tothe ra iator. Freferably, the curtainis formed in sections `with respect to a, central v 18 down and llt willflexibly connected together so that one section may be folded against anadjacent seetion to thereby vary the size of the air opening of theradiator.

As shown in Figure 2, the curtain may consist of the relatively thicksections ll, 15 and 16 connected by the flexible or hinge portions 17and 18. ln the embodiment shown the curtain consists of the outsidefabric layers 19 and 20, with the interposed pads 21, the hinge portionsbeing provided by omitting the padding at these portions so that thefabric layers 19 and 20 are in contact. rlhe padding may be held inplace by any suitable means as the stitchings 22. 'llhe padding also maybe omitted from the marginal edges of the curtain so Ithat the lfabriclayers contact to give a relatively thin part for the fasteners.

The curtain may be detachably secured to the radiator in any suitablemanner but preferably snap or glove fastenings 23 are employed. As.clearly shown in Figure 1,

llt)

these fastenings are arranged symmetrically a fastening 23 is disposeddirectly below each of the hinge sections 17 and 18 at opposite sides ofthe curtain.

From the foregoing it will be apparent that if it is desired to open upa portion of the air passage through the radiator the upper section 14:of the curtain may be folded about the hinge portion 17 down and againstthe section 20 and may be secured in this folded position by snapfastenings 24. 'lhe position of this .upper section in this foldedlocation is illustrated by the dotted line a at the right of Figure 1.lf it is desired to expose a larger portion of the air passage then'thesections 1t and 20 as a unit may-be folded about the hinge against thelower sectionv 16 of the curtain and may be secured in this foldedosition by the snap fasteners 25.

Fe observedthat each section of the curtain is detachably secured to theradiator so that a section may be unfastened therefrom and foldeddown asdescribed above. For example, the section 14k may be detached from theradiator by Vunfasteuing thefasteners 23 and when folded down theremaining sections of the curtain are Supported in their ori 'nalpositions so that they continue to 'c ose the corresponding verticalline, and

to be positioned at the edge of the shell bounding the air passageopening. This frame is held in position by being clamped between theshell and the core and preferably the fastening is made more secure byproviding a groove on one part to receive the adjacent edge of theother. Thus as clearly shown in Figure 3, the frame 27 is formed with agroove 28 to receive the adjacent edge 29 of the shell. The frame,carries the portions of the fasteners which cooperate with lthesimilarly positioned'y fasteners on the curtain. It will be seen thatthe frame 27 may be removed from the radiator merely by taking off theshell 11.

Although an embodiment ofthe invention l has been described in detail,it is to be un-Y derstood that the invention is not thus limited butincludes modifications and changes which come within the scope of theappended claims.

Having thus described the invention what is claimed as new and desiredto besecured by Letters Patent is 1. The combination with a motorvehicle radiator comprising a core and removable shell formed with anair opening at the front thereof; of a frame disposed `between the edgesof the shell bounding said opening and the core, a curtain adapted toclose said opening, and means to detachably secure the curtain to saidframe.

2. The combination with a motor vehicle radiator havinga shell formedwith anair opening in the front thereof; of a frame removably disposedat the edge of the shell bounding said opening, a curtain adapted toclose said opening, and Ineans to vdetachably secure the curtain to saidfra-me.

3. TheA combination with a motor vehicle radiator comprising 4a core andremovable shell formed with an air opening in the front thereof; of acurtain supporting frame clamped between the core and the edges of theshell bounding said opening. -v

4. `The combination with a motor vehicle radiator comprising a core anda removable shell formed with an air opening in the front thereof; of acurtain supporting frame ,disposed at the edge of the shell bounding`said opening, one of the two last mentione parts formed with a groove toreceive the adjacent edge of the other part.

5. The combination with a motor vehicle radiator comprising a core and aremovable shell formed with an air opening in the front thereof; of acurtain supporting frame disposed at the edge of the shell bounding saidopening, and formed with a groove to receive the said edge of the shell.

6. A curtain for closing the air opening in motor vehicle radiatorscompri-sing relatively thick sections connected by relatively thinportions whereby one section may be folded about a thin portion to liefiat against an adjacent section.

7. A curtain for closing the air opening in motor vehicle radiatorsprovided with spaced parallel weakened portions, thereby dividing thecurtain into sections, one of which may be folded about a weakenedportion to lie fiat against an adjacent section.

8. A curtain for closing the air opening Ain motor vvehicle radiatorscomprising sections connected by a horizontally disposed weakenedportion whereby the upper section may be folded about said weakenedportion to lie flat against the lower section, and means to fasten thesections in folded position.

9. The combination with amotor vehicle radiator, of a curtain to closethe air open- -ing in the front thereof, and fasteners to secure theedges of the curtain to the radiator disposed symmetrically about avertical center line through the curtain whereby a portion of thecurtain may be folded over against the remaining portion and the latterwill be supported by the fastenings not de.n tached and means todetachably secure said foldedh over portion tothe portion below thesame.
